Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
XmlSqlDatabaseSink
XmlSqlDatabaseSink is a sink for the Semantic Logging Application Block that exposes Event Source events to an Sql Server database. The default database sink uses a Json document to store the payload data whereas this sink uses an xml document to store the payload data.
This sink is also available as a Nuget package: https://www.nuget.org/packages/SemanticLogging.Database.Xml/
Usage
Usage is the same as with the default database sink. This sink provides one additional parameter to provide the name of the stored procedure that is used to insert the datarecords. This makes it possible to use multiple XmlSqlDatabaseSink instances that writes to different tables:
var listener1 = new ObservableEventListener();
listener1.LogToSqlDatabase
(
Environment.MachineName,
@"data source=.\sql2012;initial catalog=SinkTests;integrated security=True",
bufferingInterval: TimeSpan.FromSeconds(5),
tableName: "Others",
storedProcedureName: "WriteOthers"
);
listener1.EnableEvents(MyEventSource1.Log, EventLevel.LogAlways);
var listener2 = new ObservableEventListener();
listener2.LogToSqlDatabase
(
Environment.MachineName,
@"data source=.\sql2012;initial catalog=SinkTests;integrated security=True",
bufferingInterval: TimeSpan.FromSeconds(5),
tableName: "Sessions",
storedProcedureName: "WriteSessions"
);
listener2.EnableEvents(MyEventSource2.Log, EventLevel.LogAlways);Query payload
Since the payload is stored in an xml column it is easy to query, for example:
SELECT
FormattedMessage,
Payload.value('(/Payload/sampleProperty/text())[1]', 'nvarchar(100)') as member,
FROM TracesOut-of-process logging
